NOTE:
Follow the procedures in numerical order when performing repairs. Confirm whether the repair has been suc-
cessful using air bag warning lamp or CONSULT-III after each repair. If malfunction is still observed, proceed
to the next step. When malfunction has been eliminated, further repair work is not required.
DIAGNOSTIC PROCEDURE 3
Final Check of SRS Using CONSULT-III—Diagnosis Mode
1. If no DTC is detected on “SELF-DIAG [CURRENT]”, repair of SRS is completed. Go to step 2.
If any DTC is detected on “SELF-DIAG [CURRENT]”, the malfunctioning part has not been repaired com-
pletely or another malfunctioning part is being detected. Go to "DIAGNOSTIC PROCEDURE 2".
2. Touch “ERASE”.
NOTE:
Touch “ERASE” to clear the memory of the malfunction (“SELF-DIAG [PAST]”).
If the memory of the malfunction in “SELF-DIAG [PAST]” is not erased, the User mode shows the system
malfunction by the operation of the warning lamp even if the malfunction is repaired completely.
3. Touch “BACK” key of CONSULT-III to “SELECT DIAG MODE” screen. Touch “SELF-DIAG [PAST]”.
4. Check that no malfunction is detected on “SELF-DIAG [PAST]”.
5. Touch “BACK” key of CONSULT-III until “SELECT SYSTEM” appears in order to return to User mode from
Diagnosis mode.
6. Turn ignition switch OFF then turn off and disconnect CONSULT-III.
7. Go to SRS-18, "
SRS Operation Check".
DIAGNOSTIC PROCEDURE 4
Check SRS Repair History
1.CONSIDER POSSIBILITY THAT SELF-DIAGNOSTIC RESULT WAS NOT ERASED AFTER REPAIR
Check repair history of the SRS.
Have any previous repairs been made to the SRS?
Yes >> Self-diagnostic result “SELF-DIAG [PAST]” (previously stored in the memory) might not be erased
after repair. Go to "DIAGNOSTIC PROCEDURE 3".
No >> Go to "DIAGNOSTIC PROCEDURE 2".
DIAGNOSTIC PROCEDURE 5
Check SRS Intermittent Malfunction Using CONSULT-III—Diagnosis Mode
1. If diagnostic codes are displayed on “SELF-DIAG [PAST]”, go to step 4.
If no malfunction is detected on “SELF-DIAG [PAST]”, touch “BACK” and go back to “SELECT DIAG
MODE”.
